Jenkins · Jenkins Blue Ocean Plugin · CVE-2020-2255
**Name of the Vulnerable Software and Affected Versions**
Jenkins Blue Ocean Plugin versions 1.23.2 and earlier
**Description**
A missing permission check in the Jenkins Blue Ocean Plugin allows attackers with Overall/Read permission to connect to an attacker-specified URL. The HTTP request itself is legitimate, but only authorized users should be able to perform it. This issue affects several HTTP endpoints implementing connection tests.
**Recommendations**
For Jenkins Blue Ocean Plugin versions 1.23.2 and earlier, update to version 1.23.3 or later, which requires Item/Create permission to perform connection tests, thereby addressing the missing permission check issue.
